always be first brought to the position in which a margin stop can act.When tables have to be typed which comprise several columns the repeatedto and fro movement of the carriage requires much time.

This invention relates to a column-adjusting device for typewritingmachines comprising an ejecting cam adapted to be adjusted to the properworking position which avoids the above -mentioned incon: venience asthe margin stops can be brought into working position independently ofthe position of the carriage by means of an ejecting device arrangeduponsaid carriage. This ejecting device consists of an adjusting bodywhich is revoluble and adapted to be displaced in longitudinaldirection. so'that by the proper adjustment of this body the revolublemargin stops can be ejected rapidly and in secure succession. I In orderthat the invention may be clearly understood I shall proceed to describethe same with reference to the form of construc-.

tion shown on the wherein: Fig.- 1 is a front elevation of the adjustingdevice for the marginstop.

Fig. 2 is a plan view of the same, the adjusting rod being pulled out. Iline IX- A of Fig. 3 is a cross section on Fig 1 show ng a marginstop'in the inoperative position.

Fig. 4 is a similar View as Fig.'3, themargin stop being shown injoper'ative position.

The adjusting device for the margin stop consists essentially in a bar 1mounted in the carriage frame G and provided in the well known mannerwith the right angular recesses 2, 2 (Fig. 3) which are designed toaccompanying drawing,

guide the adjustable margin stop 8. A rod 4, mounted below the recessedbaril and parallel with the same (Figs. 1 and can ries pivotable marginstops 8 one for eajch recess 2, that is to say for each type column.

The margin stops 3consist of arms-of flat iron loosely mounted upon arod 4 and hav ing each a projecting finger'5 and a stop 6" for the catchlever of-the carriage (Figs. 3. and 4 vice, independently of the actualposition of the carriage. This ejecting device consists of an adjustingbody 7. which isfadapted to be revolved, to be moved in longitudinaldirection and toslide upon abar 8 mounted in the carriage frame-G. Atone end of According to the invention these margin stops 3 are broughtinto the operatlve position by means of an: ejecting de-;

this tubular adjusting "body/Z the ejecting cam 9 is fixed (Figs. 2 and8) which, when being oscillated, acts, according to its positionwithregard to the recessed bar 1, upon themargin stops in front'of whichit stands, so that the sameis brought in engagement with thecoresponding 'recess 2. A bar- 10 mounted along the adjusting body 7 hasgraduation lineswhich correspond with the graduation lines upon thecarriagefframe.

An angular piecel3lof sheetmetal is fixed upon the right hand-side wallof frame G of the carriage and provided with a window ll and index point12." Uponthe right hand end of the adjusting tube 7 a milled turningknob 15 is arranged which is acted,

upon by a spiral spring-14c. An angle barlf (Figs. 3 ands) with teeth 16(Fig. '2) is arranged at the lower end of the bar 1. The

front ends of teeth 16 form wedge-shaped points rounded off at'thefront, said teeth presenting' parallel side surfaces at the rear ends.Thecam-shapedbar'17 serves to ensure a positive engagementof theejecting cam 9 when the adjusting tube 7 should not be'p'roperlyadjusted." I i The ejecting of lthe" required margin stop 3 accordingtothe "desired, column adjust ment is effected in the following manner:

Suppose the carria'gevought'to be stopped at the type column-10. In thiscase the margin stop 3'ou'ght to'be brought into the operative position.This is efiected, independently of the actual position of the carriage,bypulling out the adjustingtube 7, with the a1d of knob 15, until thenumber 10 of the graduation bar coincides with the column 10. The knob15 is now turned against the action ofsprin g 14 whereby the margin stop3 is thrown into the operative position. The ejecting cam 9 bearsagainst the projecting finger 5 and brings the margin stop 3 into thepositionshown in Fig. st, in which the finger 5 bears against therecessed bar 1, the stop proper 6 projecting from said bar. The marginstops are secured in their inoperative and operative positions by alocking device which needs not be specifically described. When the knob15 is released, the spiral spring 1 L und r tension turns the body 7 andwith the same the ejecting cam 9 into the original position. In order toput in gear another margin stop the manipulations hereinba toredescribed are repeated so that without difiiculty or loss of time anynumber of margin stops in any required succession can be adjusted to theoperative position without the aid of the carriage.

The cam-shaped angle bar 17 serves; to ensure by means of itswedge-shaped teeth 16 that the ejecting cam 9 be properly and positivelyguided between two adjacent teeth.

W hen the required margin stops have been brought into the operativeposition the adjusting body 7 is returned to its original position.

Instead of the telescoped adjusting tube any other slidable body couldbe used. The adjusted margin stops are brought back to their inoperativeposition with the aid of a special device which is neither shown nordescribed as it does not form part of this invention.
